CORNER-BLOCK MOLD.

Application filed October 30, 1925.' Serial No. 65,858.

To all whom t may concern;

Be it known that I, GUs'rAv EY, a citizen of the United States and aresident of the city of New York, borough of Manhattan,

in the county of New York and State of New York, have invented a new andImproved Corner-Block Mold, of which' the following is a full, clear,and eXact description.

This invention relates to block molds and was primarily designed for usein making concrete corner blocks.

In molds constructed `with miter joints a great deal of diiiculty isexperienced in fitting the molds together after they have been used forsome time due to the fact that a certain amount of concrete or the likeadheres to the molds. `If the molds with miter joints are fittedtogether with concrete adhering to them the members are likely to bethrown out of proper alinement and the result will be blocks that arenot accurately shaped. Other types of Vmolds are constructed and thetransverse members are attached to the longitudinal members by iitting aplate on one into a slot formed in the other. This construction` is alsounsatisfactory because the slots are'continually blocked by theconcrete.

` The general object `of this invention is the provision of a simple andefficient mold so constructed that the members may be quickly assembledand disassembled.

A further object of the invention is the provision of a mold, themembers of which are provided with simple means for conneet-ing themtogether, the connecting means being so constructed that the deposits ofconcrete or the like do not cause any great amount of trouble or thepossibilityof disalinement resulting in improperly shaped blocks.

Another object of the invention is the provision of a mold, the membersof which are formed with straight sides thus introducing cheapness ofmanufacture and simplifying the replacement of worn and de-` stroyedparts.'

A still further object concerns the provision of a mold by means ofwhich a simple and eiiicient corner block can be readily cast.

The invention is illustrated inthe draw.

corner block I also provide Va hollow core Figurek 2 is a planview of aplurality of mold sections assembled.

. Figure 3 is a plan view showing various portions of one mold sectionlaid, out flat t l '60 Figure 4 is a section taken on the line 4-,-4: of`Figure 2; and ,A Figure 5v is a section taken ,on the line The form ofthe invention shown in thee 66 drawings is afpreferred form, although itbe adopted without departing from the 70 spirit of the invention as set'forth in the appended claims.

In its general aspect the invention comprises a plurality oflongitudinal wall members having hollow longitudinal headings l therein,these -beadings have preferably straightv sides. There are` alsopreferred transverse wall members likewise provided v with hollowstraight-sided headings extending longitudinally thereof. The transverse80 members are provided `with notches in the ends thereof permittingthem to be iitted `over the headings on the longitudinal members.Preferably suitable' guides are mounted on the headings of thelongitudinalv wall l members to assist in gradually locatingthetransverse members. In order tov form a member which is disposedparallel to the longitudinal wall members placed a desired cc distancetherefrom, as will be hereinafter described. This core member` isemployed and acts to close up one end of the hollow headings on thetransverse wall members to prevent concrete from flowing thereinto.y D5

In the preferred form of the invention which is shown in the drawing, Idesire to form a block having side walls 10 and 11 and an end wall 12.The side walls are to be connected by the web 13, which is connected tothe side walls by means of bracing members 14, 15, 16 and 17. Betweenone end of the web 13 and the end wall 12 is an opening which permits ablock to be readily grasped in the hand by passing the iingcrs 105through said` opening to grip the adjacent j end of the web. Thisopening also acts as a passageway for reinforcing yelements when theblock is arranged in vertical alinementV with other blocks in the wall.

To form such a block I provide a mold member with longitudinal wallelements such as 18 and 19.' These wall members, on Vone side thereof,are provided with hollow headings such as 20, having straight sides andopen ends. Mounted on the front faces of the hollow headings are guidekmembers suchV as 21 in the form of spring lingersk which assist inlocatingv certain transverse elements.

, Adapted to extend across between the longitudinal wall members 18aiid19 are transverse wall members 22, 23and 2d. `Theseare provided onltheir side faces with hollow headings such as 25. One end fot each ofthese transverse members or lwalls are provided with groovesor. cutoutportions 26, whereby they may it over thehollow beading on thelongitudinal wall member 18. On the -other end of the hollow headings 25are dis- 1 posedguide members 27 o't the type above mentioned. Theseguide members 27 are adapted to engage with the -open ends of hollowcore members 28 which extendacross between the transverse wall members22, 23 and 24 toform the aperture in the block above mentioned. Thesecore members also are formed and disposed to close the kopen ends ofythe headings A25, as is clearly shown in the drawings. Bottom plates 29and 30 are providedand assembled as shown.

-In accordance with the assemhlyshown in Figure 2,-the longitudinalmembers 18 provides an end wallfor each section and for each block form,the beading of thiseiid member forming the end groove in the block.

The beading on the transverse members forni I the longitudinal groovesin the block'. The core members extending across between the transversemembers form the apertures 'found in the block between the end wall andthe end of the wall. The open'space between the core members and thelower longitudinal wall members seen in Figure 2 :torms the end wall 12.The open space between the headings 25 mounted on the transverse wallmembers formsl the web. The slope of the by any suitable means notshown.

f low headings :mounted on said 1members- Vand ruiming longitudinallythereof, the headings on theL transverse members adapted lto abut theheadings on one of the longitudinalwall members, and' a hollow coremember extending between the transverse members and .lying adjacent theother ends of the beadings therein.

A hollow core` lmemberextending between the transverse members and abutting the 4other ends.of the headings on vsaid transverse members,` said core memherbeingspaced fromfthe other longitudinal.members to provide va space in whichan end wallfor said .block is formed.
